Features:

  • Better compression: Better than gzip
  • Slower: Slower than gzip

  • Block sorting: Uses block sorting algorithm

Why it matters:

  • Better compression: Smaller files
  • Archive format: Common format
  • Space saving: More space saved

📦 bzip2 Basics

Compress File

Basic usage:

# Compress file
bzip2 file.txt

# Creates: file.txt.bz2
# Original file is removed

Keep Original

Preserve original:

# Keep original file
bzip2 -k file.txt

# -k = keep (keeps original)

📥 Compressing Files

Compression Level

Set level:

# Compression level (1-9)
bzip2 -9 file.txt

# -9 = maximum compression
# -1 = fastest compression

Verbose Mode

Show progress:

# Verbose mode
bzip2 -v file.txt

# -v = verbose (shows compression ratio)

📤 Decompressing Files

Decompress

Extract:

# Decompress
bunzip2 file.txt.bz2

# Or
bzip2 -d file.txt.bz2

# Creates: file.txt

Test Archive

Test integrity:

# Test archive
bzip2 -t file.txt.bz2

# -t = test (checks integrity)

🔧 Troubleshooting

bzip2 Not Found

Check installation:

# Check bzip2
which bzip2

# Install if missing
sudo pacman -S bzip2
